This patch defines a bunch of new functions to use in the BFD target structs rather than casting bfd_false or bfd_true and similar stub functions. I've also renamed the stub functions to reflect their parameters and put "error" in the name if they set bfd_error. The latter change is important since there were quite a few uses of bfd_false where setting bfd_error was inappropriate, for example in elf_backend_allow_non_load_phdr and is_target_special_symbol. * libbfd.c (_bfd_bool_bfd_false_error): Rename from bfd_false. (_bfd_bool_bfd_true): Rename from bfd_true. (_bfd_ptr_bfd_null_error): Rename from bfd_nullvoidptr. (_bfd_int_bfd_0): Rename from bfd_0. (_bfd_uint_bfd_0): Rename from bfd_0u.
